The institutional directory

Explore the Castle

Every room represents a real operating responsibility.

Shared Castle Institutions provide reusable specialist capability. People belong to institutions. Work belongs to businesses.

Within the walls

Thirteen responsibilities. One Castle.

The directory records the organisational model. Status is stated conservatively and never implies more capability than is currently established.

Grouped by responsibility, not physical location.

The world & the machinery

Castle of Todd.
Hermes Empire.

Castle of Todd is the organisational and operational world model. Hermes Empire is the underlying technical estate: applications, databases, APIs, queues, model providers, connectors, schedulers, services and runtime infrastructure.

The architecture is a way to make responsibilities and boundaries understandable, not a fantasy layered over software.
